SPECIFICATION forming part of Letters Patent No.299,432, dated May 27,1884; .Application filed December 18, 1883. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM D. SMITH, a

citizen of the United States, residing at Chester, in the county ofDelaware and State of Pennsylvania, have invented certain new and usefulImprovements in \Vindows; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked which form a part of thisspecification.

My invention relates to improvements'in box or show windows; and itconsists in the construction, combination, and arrangement of theseveral parts, as will be hereinafter more fully described and claimed.

In the drawings, Figure 1 is a perspective View of my window. Fig. 2 isa vertical section thereof. Fig. 3 is a cross-section on line as m,Fig. 1. Fig. 4 is a rear elevationof the window.

The front of the window glass plates A, and a door, A, is hung at itsrear side, as shown. The sides are shown without glass, but may be sosupplied when desired. The bottom B of the window is provided near itsforward edge with an opening, B, covered by a wire or other suitablenetting or grating, B A valve, 0, is held in suitable guides closeagainst the opening B, and may be adjusted forward or back, to vary sizeof opening B or entirely close same, as will be understood. In the frontof the win dow, below the bottom B and in line with opening B, I form anopening, D, covered by grating D. An air-inlet passage or flue is formedbetween the openings D B by the in clined deflector E and the sides E.By this construction it will be seen the air can pass freely into thewindow, yet all dirt particles are excluded by the gratings, of whichI-preferably use two, D and B and make of fine net-work. At the upperrear side of the window I form an offset, F, communicating with thewindow through an opening, F, covered by wire-netting F*. This offsetextends the full width of the window, and is provided at one end with apipe, G, which extends lateris provided with ally from the window, andin use is projected into a chimney. Pipes H H extend vertically up fromthe top of the window, and in practice extend into fines or chimneys, toattain which end they may be bent and made of any suitable lengthdesired.

I have not thought it necessary to illustrate fines or chimneys, as itwill be obvious to persons skilled in building at what points and how itwill be best to open the pipes H H G thereinto.

\Vhere so desired, pipes G may be extended from both ends of the offset,and it will be appreciated that where either pipes G or H are used alonein connection with the lower opening, B, good results will be had; but Iprefer to use both pipes G and H, as before described.

I also prefer the form of lower air-inlet described and shown, asthereby the air is received directly from the open air, and is sodelivered into the window, and in its passage all dirt, &c. is stopped,and does not enter the window.

By use of the pipes O H extended and opening into the dues or chimneys,it will be seen that I get a draft of air upward through the window fromits lower. end, and that a constant upward circulation of fresh air ofequal temperature is had. This prevents all sweating of the windowcommon to ordinary showwindows. The upward draft, it will be understood,causes a constant circulation, and the air in the perature. Were theupper opening made directly out into the air, as is the lower one, itwill be appreciated that this constant circulation would not be had, butthat the air would flow into the window from both openings. By myimprovement I gain a constant even circulation, and consequently betterresults, as will be appreciated.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

1. The window substantially as described and shown, provided in itslower end with an air-inlet, and in its upper end with an air exit orexits communicating with the flues or chimneys, substantially as and forthe purposes set forth.

window is kept at an even tem 2. The combination, with a box or showwindow, substantially as herein described, having an air-inlet in itslower end, of pipes, as G H, extended from its upper end and pro- 5jccted into ilues or chimneys, substantially as described, and for thepurposes set forth.

3. The improved box or show window, substantially as described andshown, having an opening, B, in its bottom, and provided in its frontside, below said bottom, with an opening, D, connected by passage E Ewith opening B, the hinged door A, the offset F at its upper rear side,and pipes G H, all arranged and operating substantially as and for thepur- I 5 poses set forth.
